Value Collection 262-4129 Expanding Lathe Arbor 3in Face

Product Description

The VALUE COLLECTION 262-4129 is an expanding lathe arbor designed to hold and center workpieces on a lathe for turning, boring, and finishing operations. With a 3-inch face diameter and a 4-inch overall length, this arbor provides a stable mounting platform for a range of cylindrical or bored workpieces. The shank diameter measures 0.1935 inches, allowing it to seat securely in compatible lathe spindles and headstock chucks. Machinists and tool and die professionals rely on this style of arbor to achieve accurate, repeatable setups when internal-bore workholding is required. The part weighs approximately 1 pound.

This expanding lathe arbor is suited for use in manual and CNC lathe applications where a workpiece must be held from its bore rather than its outer diameter. Typical applications include finishing turned parts, grinding setups, and inspection-ready mounting of bored components. It is appropriate for use in job shops, production machining environments, and maintenance repair operations where precision workholding is part of daily workflow.

Key Features

• 3-inch face diameter provides broad contact surface for secure workpiece support
• 4-inch overall length suits standard lathe workholding depth requirements
• 0.1935-inch shank diameter for positive seating in compatible spindles
• Expanding design allows grip from the bore of the workpiece for accurate centering
• Compact 1-pound weight reduces spindle load during operation

Compatibility

Designed as an OEM-style replacement and standard-use expanding arbor for manual and CNC lathes accepting a 0.1935-inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist familiar with lathe workholding tooling. Power down and bring the spindle to a complete stop before mounting or removing the arbor. Confirm the shank seats fully and the expanding mechanism is properly engaged before initiating rotation. Follow all applicable shop safety procedures and machine tool manufacturer guidelines during setup.
